Such a material is designatedon the market as hydrol. This mate rial contains dextrose, dextrin and maltose,

' among other carbohydrates, and where sugar is produced from starch by hydrolysis, the

motheriliquor is obtained in concentrations" of 42 to 52? Baum. In addition to thein gredients specified, the mother liquor may contain nitrogenous decomposition products such" as lactic'acid, propionic acid, valeric acid and r the like. This material has the property-of augmenting the adhesive quality of proteins, such asglue, and satisfies all the requirements of. glycerine by'reason of 1ts hygroscopic nature. It is further superior to glycerine in that it gives greater body to the compound with which it is mixed. An example useful in preparing a cork composition is as follows: 1

' Example No.3 "28pounds gelatine or glue 40 pounds water 17 pounds glycerine' 1020 pounds hydrol In this example also,.the glycerine may I be. entirely displaced by hyd'rol. This mixture may be made as previouslydescribed in connection with the preparation of a sodium lactate compound for making the cork composition or as a binder for cork disks or otherwise adhering cork articlesto metal.
